T-Scan Occlusal Analysis

 

We have added the T-Scan III to our high technology equipment to allow us to analyze better and adjust our patients’ bites when we detect or suspect problems! The degree of sophistication is unbelievable since we can now record in realtime the tooth contact in 3-dimensions as you bite down and slide your teeth to the side or the front.

We record 100 progressive bite registrations per minute over a 4 to 8 sec time frame as we have you bite and hold, bite and slide left, bite and slide right and finally bite and slide your teeth forward.

We can then review the data looking at each contact every 0.01 seconds of the 3 to 10 seconds recording. The T-Scan is a grid-based sensor technology and occlusal analysis system that allows for a more natural, more accurate way to measure occlusal timing and force.

A fine/thin red/blue mylar film is usually placed between the teeth to mark where the teeth are touching; the incorrect markings are then ground off by a fine finishing bur and repolishing with rubber points with impregnated diamond paste.

 

What are some of the SIGNS that may justify an occlusal adjustment:

  • Loose or shifting teeth: sometimes one sign is increased spacing between the upper front teeth. Occasionally, you may feel that your teeth do not hit correctly.
  • Grinding or clenching of your teeth: this habit (usually stress-related) can cause an unevenly distributed and excessive biting force on several of your teeth and subsequently on the bone support which holds the teeth in your jaw.
  • Headache may sometimes accompany the grinding or clenching of your teeth and in most of these cases will occur in the temporal regions of your head (lateral to the eyes.
  • PAIN: One or more teeth may hurt upon eating or biting down normally. This pain is usually caused by the eruption of a tooth beyond the normal plane of the bite, such that only one or two teeth contact prematurely.
  • Sensitivity to temperature (sometimes hot, but mostly cold) can be due to the early contact between one or more teeth. With the knowledge that one can bite with a force of up to 200 pounds per square inch, the nerve within the tooth gets irritated and hypersensitive.
